Despite Inigo's belief on Tidus and his stomach, he's not a food fiend. The slice of cake was plenty for him - at least for now, and if that changed, it'd be much later. He's more absorbed in this conversation about blitzball. Surprise surprise.

"Make one?" --but he's especially interested, or confused about this idea Roland's cooked up. Paused, trying to think - a small sound leaving him as he explains, "Blitz pools aren't exactly small... and where would we put it? Keep it?"

He's trying to imagine any of this, but his imagination is drawing a large blank for whatever Roland's thinking.
